Van., a citizen of the United Statesand resident of Newv York, in the county and State of'New York, have invented certain new .rand useful Improvements in Rotary water motor.

In the drawings-Figure 1 is a side elevation of the apparatus. Fig. 2 is-a vertical transverse sectional view, taken on the line Fig. 3. Fig. 3 is a vertical sectional l View, taken on the pla-ne of the cylindrical compass of the casing, on the line yy, Fig. 2. 'Fig'. 4 is a horizontal sectional view, taken .on the line z-.z, Fig. 2. Fig. 5 is a side view of the rotary .cylindrical member which is eccentrically mounted within the casing. ,l

Corresponding parts in all the figures are denoted by the saine reference characters.

Referring to the drawings, 1 designates a casingwhich incloses the operative parts of the apparatus. This casing comprises side lates or members, 2 and 3, and a cylindrical member, 4, extending between said side plates -In the preferred constructional organization of theoasing, the side plates 2 and 3 are provided with annular grooves, as at 5, corresponding to and receiving the side edges, 6, of the cylindrical member 4, said joint being suitably maintained in an air-tight status, and the casing parts are secured together by a series of transverse bolts, 7, passing through portions o f the side plates which project beyond the cylindrical member 4 and operating to clamp' and bind the casing members 2, 3 and 4' securely together. The casing is mounted and retained upon a suitable supporting frame, which is preferably constituted by foot extensions of said side plates, as at 8, lwhich extensions may bebolted or otherwise suitably secured 'Application led October 12, 1910.

Specification of Letters` Patent. PatelntedlAug.. 15, 1911,

to a base upon which the apparatus is mounted in ixed\ position.-

The side'plate 3 is provided at its inner face with a circular recess, 9,- of lesser diamgleter than the `interior cylindrical compass of the casing member'- 4 and in eccentric relatlon to the cylindrical compass ofthe latter, and said ate'3 is also provided with a lateral extension, 10, at' its outerside, centrally located with relation to said recess 9. A rotary shaft, 11, is journaled in suitable bearings in said extension 10, and carries at lts outer protecting portion a gear or Y band-wheel, 12, for the application of power to or the transmission of power from said.

shaft. It will be understood that thel shaft 1 1 is thus eccentrically-mounted vwith relation to the interior cylindrical compass of the casing member 4, its'longitudinal plane being at one side ofthe true central trans-' verse plane of thelatter, and this shaft carries a cylindrical member, 14, which revolves with the-shaft and is concentric therewith and is therefore eccentric with relation to the interior cylindrical compass of the casmg. Said cylindrical member `14 is of somewhat less diameter than the interior cylindrica'l compass of the casing, and in its preferred constructional organization comprises a circular plate, 15, corresponding'to and fitting in the recess 9, and an extension or sleeve, 16,' projecting from said plate and fitting within the extension 10 and surrounding the shaft 11 and secured in fixed connection therewith by a key, 17, or in any other suitable manner, and the main cylindrical portion of the member 14 projects from the peripheral portion of said. circular plate 15 transversely across the interior area of the casing. It will thus be understood that the circular plate 15 has a revoluble movement within its corresponding recess 9,

and its seat within said recess is suitably maintained in an air-ti ht status, and in the relative positionl an arrangement the inner face of said revoluble plate 15 is on a plane coincident with the plane of the inner face of. the side plate 3. TheI cylindrical main part of the rotary cylindrical member 14 is Ipreferably constituted by a series of segmental plates, 18, collectively forming the cylindrical contour of "said member 14 and spaced apart to form intervening' slots eX- isting transversely with relation tothe interior area ofthe casing, and the annular edge of 'said main cylindrical part of the member 14, which is constituted by said segmental .plates 18, is received by and travels in a corresponding annular recess, 19, provided in the inner face of the side plate 2 of the casing said seat within the recess 19 being suitably maintained in an air-tight.. manner. -Roller-bearing' members l are operativel mountedjn the space existing between tie respective segment-al plates 18, and provide islot openings for a slidable operative connection with 'a series of radial plates, 20, to -be hereinafter described. In the preferred construction, said roller-bearing members are preferably' constituted by two sections, 21-21, between which exists a slot space, 22, through which said plates 2O project, said sectional members 21 havingy convexfouter surfaces, 23, bearing against a correspondlng concave surface, 24, upon the edge of the segmental plates 18, and said edge is preferably notched, as at 25, at opposite sides of the bearing surface 24, to

permit play of the plates 20 under the rolling action of the sectional members 21. The bearing joints between theparts 20 and 21 are suitably maintained in an air tight status. y p

26 designates a fixed supporting shaft, by which the plates 2O are revolubly sustained. Saidshaft 26 projects on a plane concentric with relation to the interior cylindrical compass of the casing, and is thus eccentric to the revolving cylinder 14 and to the plane of the-revolving shaft 11 which carries said cylinder 14, and said fixed shaft 26 is preferably secured to the side plate 2 and supported thereby and projects across the true center of the interior cylindrical-compass of the casing. The plates 20 radiate from the shaft 26 and havel a'revoluble support thereon by means of bearing rings or hubs,

as at 27, by which the plates 20 are respectively and individually carried. The plates 20 have 'a slidable bearing connection with vplate 3 and the inner face of the circular plate 15 ofthe rotary cylindrical member 14, and their outer edges contact with the inner face ,of the cylindrical casingrmember 4, at all times during the `operation of the apparatus, and said edge contacts are suitably maintained in an air-tight status.

Inthe operative eifectof the relationship of concentric and eccentric parts as above described, it will be understood that, during the rotary movement of the cylindrical member 14, which latter-is eccentric to the interior cylindrical compass ofthe casing, the radial plates 20 will be carriedby said mem?.y

ber '14 but will always maintain theirA regular projecting relationship kto the inner cylindrical face Aof the casing, said plates 20 be-- ing `mounted upon an axis Aconcentric with the interior. cylindrical compass of the cas- 'ing and eccentric to the axial center of the revolving member 14, these conditions of operation being permissible bylfi'eason of the sliding connection between said plates 2O and the member 14 through which said plates project, under the action of the rollerbearing members which are socketed in said member v14, and during the action'of said plates 20 with relation to the rotary movement of the eccentrically-mounted cylindri. cal member 14 said plates will .continuously divide the increasing and diminishing space between the circumference of the member 14' and the interior cylindrical compass of the Vcasing into separate chambers.

In the side plate'2v of lthe casing are provided chambers, as at 28 and 29, respectively coincident with vthe segmental diminishing spaces which exist at. opposite sides of the cylindrical member 14 between thecircumference of the latter and the inner Vsurface of the cylindrical casing by reason of the eccentric location of the cylinder 14 within the casing. located at opposite sides of a section of the' These chambers 28. and 29 are inner surface area of the side plate 2 which is at the central or largest rpart of said space just above referred to, and which central section forms an area, as at 30, which is on the normjal plane of the inner surface of said side plate 2. Said chambers 28 and 29 are thus related to the chambers which are formed between theplates 20, and at certain points afford communication between said latter chambers at the circumference of the cylindrical member 14. 'An inlet pipe, 3 1, communicates with the chamber 28, and an outlet or exhaust pipe, 32, communicates with the chamber 29, these pipes being preferably provided with -suitable controlling valves, as at 33. v

It will be understood that the internal chambers of the cylindrical casing, formed by the -plates 20, gradually increase and di minish in size under the movement of the plates 20 caused by the rotary movement of the eccentrically-mounted cylindrical member 14, their maximum size being reached at the area 80 of the side plate 2 which is intermediate of the chambers 28 and 29 inv said side plate, and that during the operation of the apparatus the `series of such chambers within the casing which are increasing in size are conjointly in communication with the inlet-end chamber 28 while the series of such chambers which are decreasing in size are conjointly in vcommunication with the outlet or exhaust chamv' tends down to the supply of Water in they Iber 29, but said respective sets of increasing and decreasing chambers are not in communication, by reason of the air-tight closure eected by the plate 20 which is at the. side of the eccentrically-mounted cylindrical member 14 which is in .close relation to the inner surface of the cylindrical member 4 of the casing and by reason of the closure between the respective sets of said chambers which is effected at the area-'30 of the side plate 2 existing between the chambers 28 and 29. The relative construction is such that at said area 30 two of the plates 20 will, in the operation of the apparatus, successively form a closed air-tight chamber existing between said plates 20, the circumference of they cylindrical member 14 and the inner surface of the cylindrical member 4 of the casing, and the area or plane surface 30'of the side plate 2 and the inner face of the side plate 3.

the apparatus as herein described will be readily understood by those skilled 1n the art to which it appertains. n

In the employment and p eration of the apparatus as a rotary pum to draw water from wells or mines or to raise water to required heights or for other desired purposes, the water is adapted to enter the casing 1 through the inlet pipe 31,. which exwell or mine or at any other point vfrom whichvthe water is-to be pumped. P ower is applied to revolve the shaft 11, which carries with it in its revolution the cylindrical member 14 and thus also the plates 20,

which latter in their operation have an air-v tight contact with the inner surface of the cylindrical casing and successively havean air-tight contact with the area 30 of the side plate 2 which is intermediate of the cham-l ers 28 and 29. It will be understood that the structural and operative conditions are such that an air-tight condition always exists in the chambers which are successively formed at said area 80, so that no-air can at any timeof the operation pass back into the chamber 28 into which the water enters, and that the plate members 20 operate to constantly and successively form an airtight chamber at the Varea 30, the successive formation of which. chambers draws or exhausts the air from the inlet chamber 28. This exhaust of air creates a complete or partial vacuum in the inlet chamber 28 and in the chambers formed by the plates 20 and which are constantly increasing in size and are the communication through said inlet chamber 28, and thereforethe atmospheric pressure upon the water supply with which the feed pipe 31 .communicates causes the water to rise in saidpipe and flood the inlet chamber 28 and the constantly increasingn. Y

chambers in communicationl therewith.

and is carried, by the constantly forming chambers produced by the action of the plate mem ersV 20 at the area 30 to a point beyond said area and is ejected from saidv carr ing chamber into the outlet chamber 29, in which the water pressureis estab- 75.'l

lished by the constantly decreasing conditions of the chambers which are formed by the action of the plates 20 and which are in communication through the chamber 29,

and the water is let olf under pressure at the outlet pipe 32 and utilized at the desired point. l

In the employment of the apparatus as a machanism for maintaining a circulation of water or air, the operation is substantially the same as that just described, the revolution of the cylindrical member 14 and the action of the plate members 20 produced thereby causing the formation successively and constantly of a series of chambers Which gradually and regularly increase in area as they approach the area 30 at theside plate 2 and gradually `and regularly decrease in area as they recede from said area 30,`the

series of gradually increasing chambers be' 95 ing in communication by, means of the 'inlet chamber 28 at one side of said area 30 and the series of gradually decreasing chambersv being in communication by means of the outlet chamber 29 'at the other side of'the 10;)

area 30. An operative air-tight chamber of maximum area, closed from communication with the' series of other chambers, is thus constantly and successively formed at the area 30, by which the water orair entering 10 5 at the inlet v31 and taken up by the series of gradually increasing chambers is carried in the air-tight chamber formed at the area 30 vand passed beyond said closed area 30 to the series of gradually decreasing chambers and outlet chamber 29 and forced out under pressure at theexhaust or outlet 32. Thus, when the inlet and outlet pipes 31 and 32 are in communication with water in a reservoir the action of the apparatus, under the exhaust conditions produced by the air-tight chamber formed at the area 30, ywill cause a circulation of the water in a series of pipes or coils in connection with the inlet or outpipes v31 and 32 and arranged as desired, and 120 the inlet 31 and exhausting at the outlet 32.. 12F;

cIn the general operation of the apparatus as a circulator, it will be understood that the action of the gradually increasing chambers, under the air-tight conditions hereinbefore described, causes the air to be 13" exhausted therefrom as the Achambers reach the point of'maximum area 'at the area 30 and then become an individual air-tight chamber, thus causing a suction action at the inlet side, and that the air thus withdrawn is forced out at the exhaust side bythe action Aof the gradually decreasing chambers, a continuous suction actn being thus effected during the continued operation of the apparatus In the employment of the apparatus as a turbine water motor, the head of water may be fed at the ,inlet 31, or, ifdesired, the top portion of the cylindrical casing member4. maytbe open so that the head of water enters the casing directly under the force of the source of supply, as will be readily under- Y revolution of the shaft 11, from which latter the power'can be transmitted at the gear or band-wheel 12. Coincident with the revolution of the cylinder 14 Aand its associate parts, by .action of the weight or head of water in the top chambers of the apparatus,

- the water is continuously carried o bythe closed chambers which are formed by act-ion of the plate membersQO at the area 30 and is passed therefrom to the outlet side of the apparatus and off at the inlet pipe 32. The operative action ofthe weight or head of water filling theltop chambers of the apparatus, upon the plate members 20, for the elnployment ofthe apparatus as a power motor, results from'the eccentric mounting of the cylinder 14 with relation to the cylindrical compass of the casing, and the location of the inlet with relation to the plane of the radial axial center of the plates 20,

"which axial center is concentric with the interior'cylindrical compass of the casing, whereby the preponderance of the force exerted by the water is at one side of a perpendicular plane passing through ltheftrue center of the cylindrical compass of the casing 4and therefore at the side'of the axis of the eccentrically-mounted rotary cylinder 14.' i

I do not desire to be understood Vas limiting myself to the detail construction' and arrangement of parts as herein shownand described, nor to the particular uses and employment of the apparatus as herein set forth, as it is manifest that variations and modifications 'therein may beresorted to, in the adaptation of my invention to varying conditions of use, and that the apparatus is operatively adaptable to other uses and `purposes, without departing/from the spirit and scope of my invention and improvements.
